The answer: (C) 4/5 would be .8 which makes 9 4/5 into 9.8. 1/10 is .1 which makes 9 1/10 into 9.1
Answer:
Area = 36 sq units
Step-by-step explanation:
An isosceles trapezoid have two triangles and probably a rectangle or a square.
To find the area, let's determine the height of the trapezoid.
The base length of one of the triangle
= (15-9))2
= 6/2 = 3
The height will be x
X /sin 45= 3 / sin 45
X= 3
The area of the trapezoid
= 1/2(a+b)h
Where a = 15
b = 9
h = 3
Area= 1/2(15+9)3
Area= 1/2 *24*3
Area= 12*3
Area = 36 sq units
Answer:
Step-by-step explanation: 12r-6+1= 12r-5
-8+12r+3= 12r-5
A and B
Answer:
Step-by-step explanation:
The vector AP is in the same directionas AB but its length is 1/3 of AB
No AB = (7-(-2)) i + (-2-4)j = 9i -6j.
It follows that AP = (1/3)(9i-6j) = 3i - 2j.
Now OP = OA +AP = (-2i + 4 j ) + (3i-2j) = i + 2j
So P(1,2).
Prove if R, A, C and R, O, C is congruent to each other. Is this for geometry?
